DATAI series moulded case circuit breaker is one of products developed and manufactured by adopting international advanced technology. It is supplied with rated insulating voltage 550V and 800V and used for circuit of AC 50/60Hz, rated operating voltage AC 400V (or below), rated operating current up to 1600A for infrequent changing over and starting of the motors.The products conforms to IEC60947- 2 standard.
Note: 6A without thermal protection
Type A: Without current trip-lease on N pole which making all the time, not closing and opening with the other three poles.
Type B: Without current trip-release on N pole which closing and opening with the other poles.
Type C: With current trip-release which closing and opening with the other three poles.
Type D: With current trip release which making all the time not closing and opening with the other three poles.
The thermodynamic release of a circuit breaker provides the feature of inverse time-delay, while the magnetic release is the instantaneous operation as shown on table 2(distribution circuit breaker) and table 3 (motor protection circuit breaker). Table2
